Answer:

1.6q + 10.7p + 10.2n

Step-by-step explanation:

With the perimeter they mean all sides added up together. Doing this results in a long expression:

3.5n + 6.5p + 6.7n - 7.9q + 9.5q + 4.2p

When adding terms like this, it is important to remember a rule: the numbers before letters can only be added to each other when they are linked to the same letter. So 2n + 2n becomes 4n, but 2n + 2p doesnt become 4np. When you know this, you can simplify the expression:

3.5n + 6.7n = 10.2n

6.5p + 4.2p = 10.7p

9.5q - 7.9q = 1.6q

This added together gets us 1.6q + 10.7p + 10.2n

Feel free to reach out when you need more explanation!

Answer:

1.6q + 10.7p + 10.2n

Step-by-step explanation:

Perimeter is sum of distance around, so just add all 3 sides, combining like terms.

The equation of line k is y=
Nina [5.8K]

Answer:

Neither parallel nor perpendicular

Step-by-step explanation:

I'm assuming you meant line k is y = 3x -2. If not, this is wrong.

For this, you need to put both lines in point-slope form, or the form that line k is already in. This means you only need to convert line m.

-2r + 6v = 18

6v = 2r + 18

v = 2/6r + 18/6

v = 1/3r + 3

Now you can answer the question.

To be parallel, lines must have the same slope (but a different y-intercept). 3 and 1/3 are not the same, so the lines are not parallel.

To be perpendicular, one line must have the opposite reciprocal (fraction flipped and + goes to - or - to +) of the other. While 3 is the reciprocal of 1/3, they are both positive, so they are not perpendicular.

To be the same line, the equations must be absolutely identical, which they aren't.

This leaves the last option: neither.

Let me know if you need a more in-depth explanation of anything here! I'm happy to help!

Find the circumference and area of a circle with a diameter of 22 inches. Leave your answers in terms of pi. (4 points) C = 11π;
Iteru [2.4K]

Answer:

C = 22π; A = 121π.

Step-by-step explanation:

To find the circumference of a circle, you do pi times the diameter. That would be 22pi.

To find the area of a circle, you do pi * r^2. The radius is the diameter divided by 2. That is 22 / 2, which is 11. Then, the area would be pi * 11^2 = pi * 121 = 121pi.

So, C = 22pi; A = 121pi.

Hope this helps!
